摘要

本文首先分析了光传送网络业务在故障情况下的保护操作过程

并据此创建了光网络保护/倒换时间的下限模型.仿真结果表明

网络业务的保护时间与保护倒换协议有重要关系

而光开关的动作时间对保护倒换时间的影响与网络规模没有关系.

Abstract

Based on the analysis on protection process protecting optical transport network in the condition of failure

one lower limit model for evaluating the protection and switching time is shown and validated.The emulation result shows that the protection time severely depends on protection and switching protocol

and the effect of the switch time of optical switches on protection time is independent on network size.
